Site Replication - Enforced Star Topology

Hello

My W2K3 Domain is a Single Domain with several Branchoffices (Sites).
We do have one Main Office and from there the companies policy requires
a star topology for the other sites.

I did configure the sites, assigned subnets, conifured site links. There are
two
DCs at the main site and 1 DC at each remote site. Site Replication Partners
(connections between the DCs) are managed automatically by ADS.

The Problem:

The DC at each branch office, is still trying to replicate with all other
DCs (Mesh Topology). I deleted the unwanted connections - the next day they
are all back.
I only want Remote DCs to replicate ADS and NTFRS to the mainoffice.

Any suggestions?

Thank you

So if you only created SiteLinks between Main<->EachBrandOffice
separately you HAVE a star topology by default with fail over to
full mesh if the Main DCs are all down.

It should not do this if you created separate SiteLinks for each
Branch Office ONLY with Main, e.g.,

Main---Branch1
Main---Branch2 etc.

....unless you have a DNS issue. Run DCDiag on each DC to figure out
if you have DC-DNS problems.

Describe your SiteLinks and subnets so we can review them.

You may also disable the (default) full SiteLinkBridge(grouping), but that
should NOT be necessary and the first steps are to check sitelinks and DNS
etc issues.
 
Assuming you correctly configured site links with proper metrics to/from each
site and the hub this should work.

Since it isn't, I expect your site topology is not defined correctly. I would
look for all sites being listed in a single sitelink that has a lower metric
than the other site links that have been created.

Also since you want all direct communication, you will want to disable site link
bridging. That is just one more enforcer.
